   As the omitting is now uniform, type arguments are also omitted (also in `Generic1` derived instance).

   As one side-effect, `decode` and `decode'` etc pair functions are operationally the same.

 * Move `Data.Aeson.Parser` module into separate [`attoparsec-aeson`](https://hackage.haskell.org/package/attoparsec-aeson) package, as these parsers are not used by `aeson` itself anymore.
 * Use [`text-iso8601`](https://hackage.haskell.org/package/text-iso8601) package for parsing `time` types. These are slightly faster than previously used (copy of) `attoparsec-iso8601`.
+  Formats accepted is slightly changed:
+  - The space between time and timezone offset (in `UTCTime` and `ZonedTime`) is disallowed. ISO8601 explictly forbidds it.
+  - The timezone offsets can be in range -23:59..23:59. This is how Python, joda-time etc seems to do. (Previously the range was -12..+14)
+
 * Remove `cffi` flag. Toggling the flag made `aeson` use a C implementation for string unescaping (used for `text <2` versions).
   The new native Haskell implementation (introduced in version 2.0.3.0) is at least as fast.
 * Drop instances for `Number` from `attoparsec` package.
 * Improve `Arbitrary Value` instance.
 * Add instances for `URI` from `network-uri`.
 * add instances for `Down` from `Data.Ord`.
+* Use `integer-conversion` for converting `Text` and `ByteString`s into `Integer`s.
+* Bump lower bounds of non GHC-boot lib dependencies.
